To all whom it may concern: I

Be it known that l, FRANK B.'Coo1r, a citizen of tlie United States of America, residing at Chicago, in the county of Cook and State of lllinois, have invented a new and useful Cable-Terminal, of which the following is a specification, reference being had to the accompanying drawings, illustrating same.

My invention relates to cable terminals for telephone or telegraph systems, or the like, and more particularly to cable terminals of the open type for pot-heed use.

The principal objects of my invention are to provide a sheet metal cable terminal adapted to accommodate protective apperatus .circumferentially therearound; to adapt such cable terminal to accommodate individual protector unitsn a vertical position therearound; to provide improved means for bringing the electrical conductors to the protective apparatus and properly distribut ing them; and to provide simplicity of construction, hccessibilit and durability in such a cable terminal. Other objects will be apparent from the following specification.

In telephone or telegraph systems, or the like, where cables are used, it is customary to provide a terminal at each point Where the cable conductors are .,distributed, through which the letter are connected, and to provide the terminals with protective devices to protect the cable conductors from injurious electricity which may con e to the cable over the aerial conductors. The protective devices usually provided at such cable terminals are fuses and lightning; erresters, to-protect the cable from heav' currents and from high-voltage electrici sue. as lightning. Occasionally very injurious currents of elecsuch a terminal if the latter is construct-ed of combustible material, such as wood, which lire may burn out a considerable portion of the terminal and put the circuits passing through the terminal out or" serviec.

My invention provides a cable terminal Whichis made entirely of sheet metal, with the exception of a few small insulating parts, so as to eliminate the possibility of a fire occurring at the terminal under extremely danerous. electrical conditions, the sheet metal using; formed and adapted to accommodate the protective devices which mounted thereon, and to accommodate the cubic corn doctors and aerial conductors leading to the terminal. 59inch. it sit at inetsl terminal greatly simplifies the construction of such apparatus, as the sheet metal portions are formed and punched in presses, with few operations, thus doing away with the drilling, planing and grooving of wood parts. In the terminal of my present invention the sheet metal parts do not form an air-tight inclosed portion for the cable conductors, as provision is made for terminating the cable in a potheed before it reaches the terminal and leading the Weatherproof pot-heed conductors to the terminal.

Referring to the accompanying drawings illustrating the preferred form of my invention, Figure 1. is a side elevation of the cable terminal of the invention; Fig. 2 is a phin view of Fig. 1; and Fig. 3 is a side elevation of an individual protector mountfor the terminal of the invention.

Like characters refer to like parts in the several fi ores.

The inividual protector mount of Fig. 3 forms the subject matter of my copcndin application Serial No. 356,881, filed Februar, 11, 1907.

In the accompanying drawings 1 represents a circular distributing plate around the edge of which and on the underneath side of which is mounted a series of insulators 2 2 adapted to accommodate drop Wires leading from the terminal. To the underneath side of plate 1 are secured mounting; rackets 3 3 adapted to be secured to the sides of a pole around the top therecito suitably mount the terminal on top of the pole. Sheet metal rings 4 4 are suitably held in place as shown in Fig 1 by sheet metal channel portions 5 5 and are provided with holes 6 6 the I accommodate hclts to secure the individual tricity or a high voltage will start e. lire in protector mounts, shown in Fig. 8, in place as shown in Him 1. inside of the metal rings are secured insulating rings 7 provided with holes 8 therein to acconnn'oda1e elec- L trical conductors leading from the interior of 1 pets 1.
